Vacon Beam Pump Application
1. Introduction
Select the Beam Pump Application in menu M6 on page
S6.2
.
The purpose of the Beam Pump Application is to keep a constant stroke time (SPM) by adjusting the
internal frequency reference. The control principle is to give a proper current limit for normal
operation so that during motoring cycle the motor's actual speed is less than reference but during
generating the motor speed is allowed go higher than reference, keeping the average SPM constant.
With balanced load, the application uses two different references for downstroke and upstroke.

2. Commissioning
Figure 1. Beam Pump typical torque demand.
2.1 Commissioning unbalanced load
1. Set motor name plate values
Motor nominal current must be set before the operation current limits.
2. Set proper values for START operation
Start Time
par. 2.1.18.2 Default 10.0 s
Starting Current Limit
par. 2.1.18.3 Default 110% * I
n
Starting acceleration time (
Acceleration time 2
) P2.4.3 Default 10.0 s
3. Set proper value for
Normal Current Limit
(P2.1.18.1)
Speed drops during motoring operation but it will reach the reference before the
generating cycle. If the speed drops to boost limit in normal operation you should
increase the current limit.
If the motor load increases there is no need for higher current limit because the
control principle is to increase the speed on generating side and use the pump's own
inertia to overcome higher load.
4. Set proper values for boost
Boost ON Limit
par. 2.1.18.4 Default 15.00 Hz
Boost OFF Limit
par. 2.1.18.5 Default 20.00 Hz
Boost Current Limit
par. 2.1.18.6 Default 120% * In
Boost ON Limit
should be near the minimum frequency, which is reached during normal
operation.

6. Set
SPM Regulator Maximum Step
. (P2.1.19.3) The parameter defines the frequency step
which can be made to compensate load changes. A higher value shortens the response
time, but may cause hunting on control.
7. Set
SPM regulator Gain
. (P2.1.19.2) Defines the gain of control. If the parameter is set to
100% SPM error is corrected completely within
SPM Regulator Maximum Step
. It is typical
that on start situation the adjustment is hunting. If hunting continues over 3-4 minutes you
should decrease the adjustment gain.
2.2 Commissioning balanced load
The commissioning of a balanced load is done in the same way as of an unbalanced load except for
the normal current limit. You have to select control method for balanced load.
1. Use higher normal current limit (P2.1.18.1) than in the unbalanced mode. In the balanced
mode, there is no clear generating side in torque.
2. Select proper control method at
Balanced mode
P2.1.20.1.

is above this limit higher reference allow time counter is calculating.
2. P2.1.21.2

. Time how long torque most be higher than P2.1.21.1
so that higher reference is permitted.
3. P2.1.21.3

. Torque point where High reference is activated. When
high reference allow time is full and motor torque goes below this parameter higher reference
is activated.
4. P2.1.21.4
Minimum Time at Higher Reference
. Minimum time until low reference is permitted
after high reference activaton.
5. P2.1.21.5

. Minimum time until high reference can be
activated again.

5. Description of parameters
5.1 Basic parameters
2.1.1 Minimum frequency
Defines the frequency limits of the frequency converter.
The maximum value for parameters 2.1.1 and 2.1.2 is 320 Hz. The software will
automatically check the values of parameters 2.1.13, 2.1.14, 2.3.10 and 2.7.2.
2.1.2 Maximum frequency
Defines limit for output frequency, this limit could be reached when motor is generating
side and drive tries to compensate DC-link voltage rising. If limit is reached and motor is
still accelerating due the pump mass of inertia over voltage trip may occur, if this happens
set maximum frequency higher.
2.1.3, 2.1.4 Acceleration time 1, deceleration time 1
These limits correspond to the time required for the output frequency to
accelerate from the zero frequency to the set maximum frequency (par. 2.1.2).
2.1.5 Nominal voltage of the motor
Find this value U
n
on the rating plate of the motor. This parameter sets the voltage at the
field weakening point (parameter 2.6.5) to 100% x U
nmotor
.
2.1.6 Nominal frequency of the motor
Find this value f
n
on the rating plate of the motor. This parameter sets the field weakening
point (parameter 2.6.4) to the same value.
2.1.7 Nominal speed of the motor
Find this value n
n
on the rating plate of the motor.
2.1.8 Nominal current of the motor
Find this value I
n
on the rating plate of the motor.
2.1.9 Motor cos phi
Find this value “cos phi” on the rating plate of the motor.
2.1.10 I/O frequency reference selection
Defines which frequency reference source is selected when controlled from the I/O
control place. Default value is 0.
0 = Analogue voltage reference from terminals 2—3, e.g. potentiometer
1 = Analogue current reference from terminals 4—5, e.g. transducer
2 = Keypad reference from the Reference Page (Group M3)
3 =Reference from the fieldbus
